In recent days, the Sun, which is ever approaching the peak of its activity, has sent towards Earth, not one, but several of these CMEs. Models estimate that at least three of them should hit our Earth on February 13, 2024.

Enough to trigger minor to moderate geomagnetic storms, class G1 to G2. With northern lights which should not become visible at very low latitudes.

Our Sun sometimes, when it erupts, expels kinds of plasma clouds. Astronomers call them coronal mass ejections (CMEs). In recent days, the Sun, which is ever approaching the peak of its activity, has sent towards Earth, not one, but several of these CMEs. Models estimate that at least three of them should hit our Earth on February 13, 2024.

A possibility of a strong solar storm caused by a coronal mass ejection

Enough to trigger minor to moderate geomagnetic storms, class G1 to G2. With northern lights which should not become visible at very low latitudes.

But the possibility remains for a rarer event to occur. Researchers speak of cannibalistic CME. Because not all coronal mass ejections move through space at the same speed. If one of those on its way to Earth were to be faster than the others, it could catch up with them. The combined power of these CMEs would then give rise to a strong solar storm, class G3. And potentially, the northern lights up to mid-latitudes.
